  • Patent number: 11707724
    Abstract: A preparation method of a bacterial cellulose-defective molybdenum disulfide (BC-MoS2-x) heterojunction material for treating radioactive wastewater is provided, including: preparing bacterial cellulose by the in situ growth technology of Acetobacter xylinum, and freeze-drying to obtain dried bacterial cellulose; carbonizing the dried bacterial cellulose to obtain carbonized bacterial cellulose; dispersing the carbonized bacterial cellulose into deionized water under an ultrasonic treatment; then adding thiourea and Na2MoO4.2H2O, dissolving under an ultrasonic treatment to obtain a reaction mixture, subjecting the reaction mixture to a hydrothermal reaction to obtain a BC-MoS2 heterojunction; and calcining the BC-MoS2 heterojunction in a tube furnace with an Ar/H2 atmosphere to obtain the BC-MoS2-x heterojunction.
